JONAS MOORE AND D. P. ADAMS, OF MARIETTA, OHIO.

APPARATUS FOR ADMINISTERING PULVERULENT MEDICINES.

Specication of Letters Patent No. 13,318-, dated July 24, 1855.

To all whom it 'may concern:

Be it known that we, JONAS MOORE-and D. P. ADAMS, of Marietta, in the county of YVashington and State of Ohio, have invented a new and useful Machine for the Purpose of Administering the Nitrate of Silver as a Medicine; and we do declare that the following is a full and exact description.

The nature and purpose of our invention consists in facilitating the administration of nitrate of silver in curing diseases of the throat and lungs called bronchitis and pneumonia or iniammation of the mucus membraneV lining the throat and lungs,by grinding the nitrate of silver to fine dust to be inhaled by the patient, which method of administering it obviates the unpleasant, painful and diflicult mode heretofore practiced of applying to the throat by a swab saturated with a solution of the nitrate.

The following is a description of the machine, its construction and operation, reference being had to the annexed drawings, making a part of this specification, the drawings being full size. Figure l being a vertical section; Fig. 2, is a horizontal section; Fig. 3, the tube; Fig. 4, the top of the box through which the emery wheel projects; Fig. 5, the brake and Fig. 6, the machine in the case complete.

Letter A, Fig. 1, is the case around the machine.

B, is a clock spring which drives the machine and is attached to the shaft of the cog-wheel O, which meshes into the trundlehead D, which is fastened to the shaft of cog-wheel E, which meshes into the trundlehead F, which is fastened to the shaft of the emery wheel H, which is made of wood which is coated with fine emery, on its edge. The emery is put on with copal varnish so that the emery will not come off when the wheel is washed to clean it.

I, is the brake which presses against and holds the emery Wheel from turning when the spring is wound up. The brake is made of brass or other metal with a piece of leather f, Fig. 5, which rubs against the emery wheel and is pressed against it by the spring g, one end of which rests against the block c, which is fastened to the case. The brake moves or turns on the pivot .7), and is moved by pressing the thumb against the knob K.

L, is the concentrating tube made of wood which is placed over the emery wheel, and through which the dust rises. The tube is held to its place by pins which ft into slots in the metal plate O, Fig. 4L.

M, M, are the pins.

N, N, are the slots in the metal plate.

c is a ratchet or catch wheel fastened to the shaft u, on which the wheel O turns to hold the spring from unwinding.

s, is a catch which fits in the notches of the catch wheel 0c.

P, is a spring which rests on the catch S. The spring and catch are fastened to the wheel C.

Gr, GQ'G, are the frames of the machinery.

a, is a pivot on which the knob K, turns.

CZ, is a post to which the outer end of the main spring B, is fastened.

fw, is the pencil of nitrate in the position in which it is held by the thumb and finger to the edge of the emery wheel and as the wheel turns swiftly the dust rises through the tube to be inhaled by the patient. The wheels are all made of brass except the emery wheel.

What we claim as our invention and desire to secure by Letters Patent is- The combination of the machinery described for turning the emery wheel with a discharge pipe L, for the purpose of administering pulverulent substances in cases of inflammation of the mouth and throat.
